COOL CUSHION AND SEAT.

Application filed June 27, 1922. Serial No. 571,182.

To all whom it may concern:

Be it. known that ERsKI'NE Penn HAR- LEY, a citizen of the United States, residing at Oklahoma City, in the county of Okla has invented certain new and useful Improvements in Cool Cushions and Seats, of which the following is a specification.

My invention relates to cushions and has for one of its objects, a cushion to be superimposed upon a seat, chair or other support and upon which the body of a person may rest and which will maintain ,a predetermined air space bet-ween the body and the seat or other support. The air space permits a circulation of air between the body and the seat or support.

Another object of my duce a device which 1s flexible and which will readily conform to the shape of the time maintain the air space between the body and seat or support above referred to;

Another object of my invention is to provide a structure which is porous and thereby allows air from without the cushion to replace that within the cushion through such ortions of the cushion as are not closed by the body of the person seated thereon, and at the same time allow within the cushion to contact with the clothing of a person seated upon the cushion.

Another object of my invention is to produce a structure which will permit the body of the person seated thereon to move relativ to the seat or other support without relative movement of the body and seat or relative movement of the seat and support, thereby eliminating wear upon the clothing or upon the support, which may be very obinvention is to projectionable if the support is covered with fabric subject to wear and at the same time such movement is much less annoying to a person seated thereon.

Further objects will be disclosed hereinafter.

' My invention resides in the new and novel construction, arrangement and combination of the parts hereinafter fully described and shown in the drawings.

In the drawings accompanying this specification:

Figure 1 shows my invention comprising a seat and back. portion flexibly hinged together.

Fig. 2 is an enlarged view in. part of the air circulating Fig. 1 to show clearly the details of construotion.

Fig. 3 is a modification as relates to a detail in construction giving stability to the'device.

My invention comprises two ortions; namely, a back and seat portion and B respectively. Each portion A and B comprises a spirally wound coil spring F usually made of small steel wire with the coils of the spring substantially vertically disposed'with respectto the plane of the section A or B and may be spaced apart to form a supporting structure which will permit the free circulation of air through the member F, to give the proper strength to support the body, and in which the convolutions are free to move relative to each other in order to conform readily to the body and give flexibility and cushioning effect to the structure. The convolutions of the member F reside substantially in a common flat plane except when forced out of such plane by pressure from without. The forming of the convoluted member F usually starts at the center and the coil springis wound upon itself about a common axis which forms the center of the'section A or B, and until the proper number of convolutions is secured to give the diameter required. I

In order to prevent each section from buckling and to cause it to maintain its shape and the back to stand up, I employ an outer of each section to a suiiicient degree to give stability to each section, but not to be unyielding to the extent of inconveniencing the person seated. The member G, which I will term a rim, as shown in Fig. 2 is a spirally wound member similar to that of member F, but may be composed of a wire of larger diameter and wound much closer than the member F. The yielding member F maintains an air space between the body and the support and the member G stifl'ens and gives stability to the structure.

A modification of the member G is shown in Fig. 3 and comprises a coiled member L similar to that of F enclosing the ring M usually of flexible metal.

If the article is to comprise a seat and back section, two convoluted members F and G are prepared and assembled as shown in Fig. 2 or the members F, L and M are assembled as shown in Fig. 3, and these are member G to stiffen the periphery covered on both faces with one or more apply to the outer face of the front "andback portions of the covering, and along that portion where the sections are being bent back and forth, a strip of heavy webbing H stitched in place as indicated at C.

The members D and E on the front. and back of each section are stitched around the edge outside of the rim G and close thereto. A Webbing I is then applied to the outer raw edge of the members D and E and stitched thereto as shown. The webbings I and H are also stitched together as indicated.

The members D and E I' prefer to make of a coarsely woven fabric and may be of various materials, as forinstance, it may be woven from paper yarn which, I find, is tough, absorbent and will resist wear, or it may. be of cotton or woolen yarn.

In order to give shape to the binding edge I and maintain its shape and also to add a slight stiffness to the binding edge I, I

insert therein a small wire member J which I prefer to make of steel or phosphor bronze wire possessing resiliency. This member' J is not continuous across the line of fiexure between the back and seat portions.

If the sections are made separate for use as a seat or back only and which are convenient for use on stools and as porch seats, a similar construction will be carried out as described above and will be apparent to one skilled in the art, and where the sections are separate they will usually be shaped round although my method of construction lends itself readily to other shapes.

7 In order to keep the back section in place When in use, I detachablysecure-to one of the sections a tab K provided with button holes K whereby the tab may be secured to a button secured to the main seat or support. The tab K is also convenient in maintaining the sections in a completely folded relation for convenience in carrying, as the tab can be brought around and over the edge of the two folded sections and secured to the opposite section by means of a button secured thereto as will be evident.

I claim: a

1. An article of manufacture comprising an enclosed member, a convoluted member within the enclosing member to hold the enclosing member distended and means separate and independent of the convoluted member circumscribing the convoluted member within the enclosing member to give stability to the structure.

2. An article of manufacture comprising an enclosing member, a convoluted member within the enclosing'member to hold the enclosing member distended to permit free circulation of air therein and means separate and independent of the convoluted member, circumscribing the convoluted member to give stability to the structure.

3. An article of manufacture comprising an enclosure of a plurality of fabric members, means for holding the enclosure distended and allow free circulation of air therein and means comprising a separately formed and independent ring circumscribing the holding means for giving stability to the structure. I

In testimony whereof I aflix my signature.
